Rear mech/hanger - advice needed!

Hi All,

I've got a Kona Splice 29er 2012 and yesterday the rear mech managed to bend into the spokes and bring my ride to a sudden crunching halt.

I went to Halfords this morning and they advised me that my rear mech and hanger are both bent and in need of replacing. I have a couple of questions:

1: Are rear mechs universal? Do I just need to go for a Shimano Acera SGS or could I spend a bit more and get something like the Shimano Alivio M410 and do a like-for-like swap? I want to get the best for my buck but don't want to start having to replace other components to accommodate the new mech

2: It looks like I need hanger #27 for this bike, but is about £20 the right price? Are chepaer eBay ones any good?

Thanks in advance,
